Toallwhomitmycomei'nf '1' Be it. known that I, SILAS P.'Pnrnnson, citizen: of the United States, residing at Princeton, in the county of Bureauand State I of Illinois',;. have invented certain new and useful Improvements in Combination-Tools, of which t e following is a specification. v .My-invention 'relatesto anew and useful improvement in combination'tools, and has 19- for its object the embodiment of several articles in one tool. which may be easily carried upon the person.

It has for itsfurther object novel means for assembling the several parts which will bemore clearly -understood from the follow mg specification and drawings, in which igure 1 a plan view showing one blade open ;'Fi ,2 .is a longitudinal sectional view of one si e of the too and Fig. 3 is a longitudinal' sectional view of the opposite side of the toolmFigA is -a detail showing the calipenrgady for use. In thefllrawings the numeral, 1, indicates a handle constructed as the ordinary pocket upon its up er edge is provided a gra uhted scale, 2. ivoted within the handle are the three blades 3', 4., and 5, of which 3 is the small blade, 4 the medium sized blade, and 5 the larger blade. The large blade 5 is provided with the graduated scale 6 along its upper edge, and this scale is in alinement with the scale 2 of the knife handle when 'theblade is opened, as clearly shown in Fig. 1. A plate, 7, divides the handle into two compartments and the. largeand small blades are pivoted within one of the compartments, whereas the medium sized blade is within the other compartment; Secured along the upper'edge of 0 the knife are the, ordinary. springs, 8 and 9, which hold the blades in their open and closed positions. The spring, 8, is somewhat smaller than the spring, 9, and is rovided upon its edge with a nail file. A ong the 5 upper edge of the spring, 9, is a somewhat coarser nail-file and match scratcher. The blade, 4, is of theshape shown in Fig. 2 so that the end, 10, will engage the spring, 8, and the edge of the blade will be somefdistance separatedfrom said spring.

1 Slidably secured within the same com )art- 'nfe'nt with the knife,-4,is a caliper, 11, av-

ingithe' scaled shank, 12. Secured just below the shank of; the caliper is the metal block, 13, which holds and guides the caliper against the s rin 8.- whereby thecaliper Specifics/done; Letters Patent.

'will be held in any position. The spring,

is notched as shown at 14 and operating \Lithin this notch is a pin 15, which .limits t e movement of saidspring, so that the,

end of the handle is notched as shown at 16, 1

so that when the caliper is extended for taking measurements the scale can be easily read,

the point 17 serving as a pointer.

From the foregoing description several parts it is thought that the operation of the tool will be clearly understood. It will be seen that the tool may be used as the of the ordinary pocket knife, as a measuring inst-rument, as a caliper, as a nail file, or as a match scratcher, or in fact, for a number of other uses which will be readily apparent. By opening the large blade, 5, it will be seen how the tool may be used as a measuring instrument, and in fact it may be used as a measure for measuring short distances without even 0 ening the blade.- The caliper, 11, ma be rawn out to any desired distance and Wlll be held in place by meansof the spring, 8. This caliper may be used for any desired purpose, such as ascertaining the exterior or interior diameter of a pipe, nut, bolts, etc. By referring to Fig. 2 it will be seen that the blade 4, being of the shape shown, will not in any way interfere with the caliper and the same may be freely operated.

The use of the tool as a nail file or match scratcher is so apparent that it is thought no remarks as to the same are necessary.

it is evident that more or less slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hencel do not wish to be limited to the exactconstruction herein set forth, but:

Having fully described my invention, what I claim as now add desire to secure by Letters Patent is:

1. The combination with a handle having blades pivoted therein, of a caliper adapted.

to slide within the handle pndsprings adapted to engage both the'bladcs and call; or

whereby th'oy are held in position.

2: The combination with a handle huvin blades pi voted thereon, of a caliper adapted to slide withm the handle, and springs adapted to engage both the blades and caliper for holding the same in position, said springs rovided with roughened upper surfaces a apted to beused as nail fi es and match scratchers.

3. The combination with a handle havin blades pivoted therein, of a caliper adapte to slide within the handle, and springs- 4 adapted to engage both the blades and calisaid per whereby they are held in position,

springs provided with openings and connecte operate in the openings for limiting the movement of the spring.

4:. The combination with a handle-having to the handle and edapte to blades pivoted therein, of a caliper adapted to slide within the handle, springs adapted 15 to engage both the blades and caliper for holdin them in osition and a block secured in the andle and ads ted ta act asa guide for the caliper and to old the same against the spring. f

In testimony whereof I afiix my signature, in the presence of tw0-witnesses.
